Описание

The MAX5971BETI+ is a single-port, 40W, IEEE 802.3af/at, PSE controller with I2C in 28 pin TQFN package. This device provides powered device discovery, classification, current limit and DC and AC load-disconnect detections. The device supports detection and classification operation from a single 54V supply. In addition, it supports 2-event classification and new Class 5 classification of high-power PDs. The device provides four operating modes to suit different system requirements. By default, auto mode allows the device to operate automatically at its default settings without any software. Semiautomatic mode automatically detects and classifies a device connected to the port after initial software activation, but does not power the port until instructed to by software. Manual mode allows total software control of the device and is useful for system diagnostics. Shutdown mode terminates all port activities and securely turns off power to the port.

• Supply voltage range is 32V to 60V
• Operating temperature range from -40°C to 85°C
• Up to 40W for single-port PSE applications
• Integrated power MOSFET and sense resistor
• Supports 54V single supply operation
• PD detection and classification
• I2C-compatible, 2-wire serial interface
• Instantaneous readout of port current through I2C interface
• Programmable current limit for Class 5 PDs
• High capacitance detection for legacy devices
